Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed July 27,1905. Serial No. 271,442.

To all whom, it may concern.-

Be it known that I, JAMES M. ASKINS, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Automatic Flushing Closets, of which the following is a specification.

My invention relates to a device which is especially designed for flushing closets or so supplying a body of water to flow for a limited period at such points as may be desired.

It comprises a combination of parts and details of construction, which will be more fully explained by reference to the accompanying drawings, in which Figure 1 shows the application of my' de vice. Fig. 2 is an enlarged view of the lever arrangement. Fig. 3 is a sectional view showing the mechanism which operates the tank-valve arm.

I have shown the device as applicable to flushing closets, and, as shown, A is a lever fulcrumed, as at 2, and having a weight 3 from one arm of the lever. The other arm is connected with a seat or part, as at 4., which the weight is heavy enough to keep normally raised while in position, and when any weight is placed upon this end of the lever or the part with which it is connected the end connected with the seat will be depressed and the opposite or Weighted end will be allowed to rise.

5 is a cord or chain connected with the longer weighted arm of the lever, and the up per end is fitted to coil upon a pulley 6. This pulley may be weighted at 6 or springpressed, so that as soon as the tension upon the cord 5 is released the pull will turn it a certain portion of its diameter.

7 is a pin projecting from the face of the pulley and turnable with it.

8 is an arm or bar one end of which is connected with the bell-crank lever 9, fulcrumed, as shown at 10, and this lever is connected by a rod 11 with a lever 12, which is so connected with the valve within the tank 13 that the pulling down of the lever 12 will open the pin 7 registers with the notch 15. The arm 8 normally rests upon a fixed pin 16, and the operation of this part will then be as follows When the lever-arm A is tilted and the cord or chain 5 relaxes so that the pulley 6 can turn the pin 7 passing under the end of the bar 8, which extends across the face of the pulley, will raise this bar from its bearing on the pin 1 6, and as the pulley revolves the pin 7 will arrive at a point in line with the notch 15 so that the latter will engage with the pin. The parts will remain in this relation as long as the lever A and the part connected with it are depressed. As soon as these parts are released the weight 3 will depress the opposite end of the lever A and pulling upon the cord 5 will rotate the pulley backward toward its normal position. The pin 7, pulling against the notch 15 in the bar 8, draws this bar with it, and this, acting through bellcrank lever 9, connecting-rod 11,and valveactuating rod 12, will open the valve to allow the discharge of water. As the pulley 6 revolves and the pin 7 begins to descend with relation to the pulley center the bar 8 will rest upon the pin 16, and this allows the pin 7 to become disengaged from the notch 15 when the rod 8, lever 9, connecting-rod 11, and valve-lever 12 will resumetheir normal position and allow the flushing-valve to close. The parts are then in condition to be again operated. In this manner the flushing oper ation becomes automatic.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination in a flushing device, of a fulcrumed depressible weighted lever, a revoluble pulley, a cord or chain connecting the lever with the periphery of the pulley, a notched bar extending across the face of the pulley, and a support upon which said bar normally rests, a pin carried by the pulley adapted to engage the notch of the bar, and connections between said bar and a watercontrolling valve.

In testimony whereof I have hereunto set my hand,in presence of two subscribing Witnesses.

JAMES M. ASKINS.
